The ZT6000e zero-turn mower is powered by a 20.4-kilowatt hour, lithium-ion battery. It produces zero emissions and delivers productive runtimes in commercial applications. On a single charge, it provides up to eight hours of runtime and mows up to 23.8 acres, depending on conditions. This turf-taming machine can be fully recharged in 6.3 hours with a 240-volt connection, or in 12.6 hours using a 120-volt connection. Apart from routine recharge cycles, the powerful lithium-ion battery requires no maintenance for the life of the machine.
